How does Ralph feel the morning after Simon is killed?

Ralph is the only boy who truly recognises the significance of Simon's death. Piggy is ready to lay part of the blame on Simon himself and the dance, the Twins are in total self denial and Jack dismisses the entire episode as a 'trick' played by the beast. Ralph alone gives the deed its true name, murder, and Ralph alone seems to realises the depths to which they have sunk and the ferocity of their attack. Ralph too realises that having gone this far Jack and his tribe are now capable of almost anything.
